PBP don't compile as this tight. There's other compiler (BASIC, C) that provide tighter code than this. but PBP is mature and... 99.8% bug-free.

I like to build my own tight and optimized routine, some are self expanding, meaning that if some feature aren't used, this will not INCLUDE the un-necessary code. PBP do it as well... in it's own way. There's place for optimization so far.
